How this is calculated
Divides your ad-driven revenue goal by your target ROAS to get a budget. If you also enter your total expected revenue (ads plus organic), it separately checks what your TACOS target implies for a budget, so you can see whether your ROAS and TACOS goals actually agree with each other.
Budget from ROAS = revenue goal ÷ target ROAS. Budget from TACOS = total revenue × target TACOS %. These two numbers only match when your assumptions are internally consistent — a real mismatch usually means one of the two targets is unrealistic for the other.
